电磁学

前言

　　This is an intermediate-level textbook on electricity and magnetism. It is intended to be used for a two- or one-semester course for students of physics， engineering， mathematics， and other sciences， who have already had a one-year introductory physics course with calculus.　　The book is flexible enough to be used in several ways: （1） The traditional two-semester course would cover electrostatics and magnetostatics in the first semester using Chapters 1-8; and then magnetic materials and time-dependent fields in the second semester using Chapters 9-15. （2） An instructor teaching a one-semester course could cover all the basic principles of electromagnetism by using Chapters 1-3 and 6-11; there might also be time for a few examples from Chapters 4 and 5. （3） An interesting alternative approach in a two-semester course would be to go over the basic principles of Chapters 1-3 and 6-11 in the first semester， and then applications and advanced topics in the second semester based on Chapters 4，5，and 12-15.　　The total material in the book is more than could be realistically covered by any instructor， even in two semesters. Instructors are encouraged to pick and choose based on their own judgment of what is important. Electricity and magnetism is a wonderfully interesting subject， but to students at the intermediate level its phys-ical concepts are non-intuitive， and the associated mathematical techniques are new and challenging. Therefore its important in teaching this subject to avoid the kind of heroic pace which will tire out all but the strongest students and instruc-tors. The general principle that in teaching its better to uncover a little than to cover a lot， applies to this subject of course.　　The order of presentation of subjects is the traditional one: electrostatics first， then magnetism， electrodynamics and Maxwells equations， relativity， and radia-tion. Chapter 2 is an introductory treatment of vector calculus， which should help students acquire the necessary mathematical armamentarium. Our experience in teaching this subject is that at the outset of the course most students do not know vector calculus well enough to study electromagnetic field theory， so its impor-tant to help them gain the necessary mastery. Chapter 2 is sophisticated in places，and it is not necessary to comprehend all of it before starting on Chapter 3; the student can return to Chapter 2 when additional mathematical skill is needed. Stu-dents might also read a specialized book on vector calculus （e.g.， one of the two references at the end of Chapter 2） while studying Chapter 2.
